CARH EATER.

SPECIFICATION forming part of Letters Patent No. 383,835, dated May 29, 18:88.

Application tiled February l), 1867. Serial No. 228,243. (No model.)

To all whom t may concern:

Be it known that I, JOSEPH W. SToRRs, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Car-Heaters, of which the following is a specification.

This invention relates to improvements in carheaters, and has for its object to prevent the escape of the heated coal from the tire-pot in ease of collision or other accident on the road, whereby t-he danger of lire is avoided.

The invention consists in the novel features inafter fully described and claimed, and illustrated in the accompanying drawings, in which#- Figure l represents a vertical section inthe plane w x, Fig. 3, of a heater embodying my invention. Fig. 2 is a similar section in the plane y y, Fig. 3. Fig. 3 is a horizontal crosssection in the plane z z, Fig. l. Fig. 4 is a similar section in the plane x Fig. l. Fig. 5 is a sectional detail view of a door-lock. Fig. 6 is a vertical central section of a modification.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the outer metallic jacket or case, which extends from floor to roof of the car, and is provided with. a metallic top and bottom whereby a strong protection is formed for the inclosed jacket B, which is best made cylindrical in crosssection,andissecured,respectively,at top and bottom to the outer jacket or case, A, so as to form an inner isolated airspace, C, in which is located the heater or stove D, the smoke-pipe d of which extends through the top of the casing A and above the car-roof.

To prevent the hot coals on the grate d' from escaping through the smoke-pipe d, in case the heater is overturned, I provide a closing-plate, E, Figs. l and 4, which is located near the top of the heater, and is perforated or slotted, as best seen in Fig. 4, to permit the gases of combustion to pass through. This plate E is provided with legs e, which Aextend through slots in the heater, said legs resting at the end of the slots.

The plate E is provided with a head, e', which is adapted to close against the pipe d, and on said head is formed a catch, e, that is engaged and retained by spring-arms e3, seA cured to the exterior of the smokepipe d and entering the same. A closing-weight, F, which can be in the form of a ring encircling the eX- terior of the heater, and movable thereon, engages with said legs e on the closing-plate E, and forces the latter into contact with the springarms e3, and thereby closes off the exit of coal in this direction. Flanges ff' on the closing-plate close up the slots when the former is in either position.

The closing-weight is normally supported on pins or supports ff, Fig. 1, secured in the heater. By providing means for holding the closingplate in its closing position, as by the spring-arms e, subsequent movements of the stove which may move the weight will not affect the closing-plate. The rod f of the damper extends through both jackets A B, and can be turned from the platform of the car. Air is supplied to the heater beneath the grate through a Supplybpening, G, which is closed by a door, g, Fig. 1, having openings, as usual, which can be closed, as desired, and said door is lined on its inner side with a strong perforated plate, g.

Air is supplied to the chamber t) by an inlet-flue, H, extending above the roof, and en tering the chamber near its bottom, as at h. The top end of the iue H is closed, and near the same are a number of holes or perforations, h', Fig. I, through which the air can enter. To close said holes, in case the car topples over, I provide an annular sliding gate, H', which its loosely in the flue and rests on the supports h. If the heater is overturned, the gate H slides, owing to its weight, and closes said holes, and it is retained in its closing position by springlocks h2, extending into the interior of the said flue. The heated air from the airchamber O is led away by flues I,open ing at z' z', at the top of the same, and leading downward and out at i', and thence through the car, or as may be desired. The openings ot' the iiues I and H into the air-chamber C are closed by perforated plates j j and g2, to prevent the escape of heated coal in case such should escape from the heater, and, as an additional safeguard, I provide heavy sliding gates J J, located in said flues and resting on supports j j. These gates J .I act in a similar ICO manner to the gateiI-/ of the flue H. The door K of the heater is arranged to slide, and is provided With a spring-handle consisting of a spring-pressed bell lcrankleverJaFig, having a handle, k,one arm of which lever is provided with a pin or catch adapted to enter a socket, k2, formed in the heater. When the handle is moved to slide back the door, the pin is released from the socket, and when the door is closed the lever automatically locks the same, whereby it is prevented from opening in ease of accident. Access can be had to the heaterdoor K through openingsin the jacketsA and B. The door L for the opening in the jacket B is constructed similarly to the heater-door K; but the door M in thejacket or casing Ais arranged to slide vertically, Figs. l and 3, in proper ways. It can be retained in its open position (when up) by a lock, Z,and is retained in its closed position by a springbolt, Z', so that it will not fall open accidentally.

From the above description it will be observed that all the doors are automatically locked when closed, and all other ports are so constructed that the heated coal cannot escape under any circumstances, the two jackets being strong enough to prevent the stove from being crushed.

As illustrated in Fig. 6, the air-supply flue H can extend directly into the air-chamber C from top down, whereby the opening h in the jacket B is dispensed with. I also make use of but one flue, I, which is placed centrally with respect to opposite sides in the jacket or casing A, so that if the car falls over on either side heated coal cannot enter the opening z'. I also provide the door L of the jacket B,as an additional safeguard, with a heavy or weighted gate, L', which works in slides S on the said jacket and closes over the door by its own weight when the heater is overturned. Stops are provided, or a lock, S', may retain the Weighted gate When closing the door-opening.

The roof of the car can be made of sheet metal, Fig. 6, and the heater being but lightly secured to the bottom of the car, the heater will readily detach itself from the same in 'case of accident, thereby reducing the danger of re to a minimum.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a stove, D, having a smoke discharge pipe, cl, extending from its top, cfa closing-plate, E, having legs c, and a head adapted to close the lower end of the smoke-pipe, and a weight arranged below the closing-plate and slidable on the stove-body to strike .the legs of the closing-plate forclosing said lower open end of the smoke-pipe, substantially as described.

2. The combination, with a stove, D, having a smoke-pipe, d, provided with a ret-ainiugdevice e3 of the closinglateE havin r leffs e a 1 up i s :s

and a head, e', provided with a catch, e, to engage the retaining device, and a weight, F, arranged below the closing-plate and slid.

able on the stovebody, substantially as cle-' scribed.

3. The combination, with a stove, D,'haviug a smoke-pipe, d, extending from its top and provided at its top with slots,of a closing-plate, E, having legs e, extending through said slots, and a weight, F, slidable on the body of the stove to strike said arms and force the plate to close the lower open end of thesmoke-pipe, substantially as described.

4. The combination, with the closing-plate located in the'interior of the heater and in line with the smoke-pipe, of a Weight extending about the stove, supports for said weight, legs on the plate extending outward and adapted to be engaged by the weight, andv a retaining device for the plate, substantially as shown and described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
